~~~~~~~~~~~~~~~~~~~~

This problem is about solving a compound inequality

    700000 <= 496000 + x <= 750000.


To solve it and find x, subtract 496000 from both sides

    700000 - 496000 <= x <= 750000 - 496000,


which gives the 


ANSWER.  She can spend from $204,000 to $254,000 and to be still within her estimate.

Solved.
